The symptoms of a stroke differ depending on the type of stroke, according to WebMD. The three types of strokes are ischemic strokes, hemorrhagic strokes and transient ischemic attacks. Symptoms of all strokes come on suddenly. A person exhibiting any of the warning signs of a stroke should call 911 and see a medical expert immediately to avoid permanent brain damage.

A person who believes that he has suffered a stroke can test his body through a number of exercises. The patient should try to raise both arms, and if one arm begins to fall, then the person may be having a stroke, according to the Mayo Clinic. Slurred speech often occurs in patients having a stroke. Stroke patients may experience double vision or blackened vision in one or both eyes. It is common for stroke patients with headaches to experience vomiting and altered consciousness as well.

A stroke takes place when there is an interruption in the flow of blood to the brain, explains Mayo Clinic. This causes death of brain cells because they are starved of oxygen and nutrients.
